The lambda is showing lean but you have a lot of unburnt fuel coming out the back there. Is that on standard management? Not sure a cat will cure that

Lambda of 1.5 is lean, you will prob have to adjust the fuel map and probably the ignition one too if you want a legal MOT on that one

edit: unless its not burning the fuel right because of the ignition timing and its fooling the machine into reading lean. Is that done on a base map or has it been setup for the car?

There seems to be a lot of unburnt fuel which if you put a cat on with out adjusting the map will destroy the cat. However lambda shows its running lean? Is the ignition timing good?

prob why it was popping at the revs

thing is holding at 2500rpm is on so little throttle,

the car settled at lamba of 1.04 after 5minutes of holding it at 2500rpm, the the hc settled at 300-400 and the CO went sky high

Im not being funny or anything, but if it were mapped right it wouldn't have emissions like that.
Thats not a dig at whoever mapped it btw.
